Need help. My Transformer won't charge anymore

[Alta1r]

Hi,

I hope someone can help me. My Transformer doesn't charge anymore since yesterday.
Tablet was around 10% when i put the charger in, but the message 'Connect your charger'doesn't go away.

Strange thing is that whenever i plug it in and TF is off, it will turn on, so I guess the wall charger and cable are functioning.
Also when connecting it to my PC I can sync.

I've tried already all the solutions i could find online:
- put the wall charger in the freezer --> didn't work
- cold boot --> didn't work
- factory reset --> didn't work
- tried a different wall charger and connected the wire to a portable battery --> didn't work
- flashed the ROM again --> didn't work

The only way now i have for charging my TF is by USB (connected to PC while turned off). It will charge this way but it takes about 3 hours to get 10% charge from this.

Anyone had this happen already before?

So you tried multiple Asus wall chargers? with no luck? A standard USB charger will not work as those have an output voltage of 5+ when the tf requires 12+.

Sounds like you have a bad charger, you can join the club of thousands... It is a very common issue and not always resolved by the freezer or fiddling trick. If you are able to trickle charge via a PC connection then your cable and tf should be good.

It really is heads and tails better than the Asus one

No, I tried with a different wall charger (from Motorola). I don't think it's the wall charger though, but to make sure I wil connect it to a phone and check if it's working.

It just feels like the cable and wall charger is working as it should (tablet powers up or screen turns on when I plug it in), but the tablet refuses to charge.

Could it be the pins?

And the motorola USB charger puts out at least 12 volts and not just 5. Is it the wall charger for the zoom? I was UN aware that the zoom used a USB type charger (similar to the tf).

Once again, you can't use just any USB wall charger for the tf... 99% of chargers put out the standard 5 volts which is enough to trickle charge a tf and to slightly charge it in done cases when powered down. I am only adamant about this this because I have sewn this post a hundred times, and 99 of those times it was the charger... Many people don't realize the tf USB charger is very coherent then what most folks are accustom to, even though it looks and acts similar to others.

The only way to confirm is to find someone who has a tf and borrow their charger, our go to radio shack and buy the charger I listed... Which you should do any ways because it's is way way better, my charging cord over all length is 10ft. Beats the hell out of the 2 or 3 you normally would have.

Thanks for your replies.
You're right, the Motorola wall charger is only 5v output. It was the one I got with the Milestone. I do start to believe it might be the wall charger after all now.

Unfortunately I don't know anyone else with a TF (anyone reading this lives in Ghent, Belgium with aTF?). Radio Shack isn't an option either since I live in Belgium, but I'll try to find overhere or online.

Anyway, appreciate your help. Might try the freezer thing again in the meantime... you never know.

When you connect your TF to a pc on a usb 3.0 port, should you be able to see the TF charging? Or no way to get more the 5v from this too?

USB is 5V. No exceptions.
What you can do is build your own PC charger, like the one in my sig.

Cheers man, my colleague has an ipad. Will ask him to bring his wall charger.

I might try that, but only if I have no other choice (i fear i'll blow up my TF while doing that).

usb chargers are 5v only and will charge but take all day. The TF charger uses the physical usb plug to do double duty. transfer data via usb and charge device using 15v when the charger block sees a gnd signal on pin 7. Charging is not usb. There are several after market chargers that have variable output voltages and an asst of connectors (usb being one) best one is dynex video charger. Also you should not attempt to flash a ROM with 10% charge as you could get stuck in the middle of a charge and have problems.

Well, it was the wall charger after all. Went out to buy a power adapter with 12v and 1000mA output and the tablet is charging again. Many thanks to all people that replied and tried to help me.

For your info: ipad or galaxy wall charger aren't working with our TF's, they both only have an out put of 5v.

Never allow your charge level fall below 30% because it will cause your charger to overheat and eventually stop working.
